Indeed, it's wait.
However, I was trying to reproduce the problem in a VM by removing SATA 
disk on the fly from raidz2 (while pool was under I/O by bonnie++ ), and 
it worked correctly - drive state is "REMOVED" in "zpool status" command.

But the pool works correctly.


Taking into account this PR, I am wondering if it might be a hardware issue:

Thanks - I will try it out.
